This invention relates to automobile bumpers and more particularly to bumpers which are adapted to be ap lied to each side of the rear of an automobi e'for the protection of the fenders.

It is the 'gener'al'purpose and object of this invention to provide a: resilient bumper which may be convenient-1y attached to the rear of an automobile and which willbe supported in such a manner as to eliminate vertical and. horizontal vibration. It is a further object of the invention to provide a bumper and support which will be of suflicient strength to afl'ord adequate protection to the automobile in'resisting an impact directed toward the fenders.

Further objects of the invention will appear hereinafter and will be realized by the use of the combination of elements set forth in the claims.

In the drawings, Fig. 1. represents a planview of the bum er as attached to the rear'of an automobile; ig. 2 represents aside elevation of the said bumper; Fig. 3 a detail in section corres onding to the line 33 of Fig. 1; Figs. 4 and 5 show detailed views of modified means for attaching the bumper to the -automobile.

For convenience of description the bumper 'will be assumed to be in position at the rear end of an automobile and the terms rear and front will be used in reference to such location, thoughit is not intended that the attachment should be necexarily. limited to any particular part of the vehicle.

The invention will be fully described by reference to' the following characters onthe if drawings; 1 denotes theimpact element which is here shown as made up of two vertically spaced spring steel bars, 1 and 1, conv nected at their ends by-means of pins 2 and 3 assing throu h'eyes at the ends of each bar. he impact element is supportedb spring steel bars attached at their forwar ends to the automobile frame and having eyes at their rear ends interposed between the upper and lower impact bars 1 and 1" and in vertical alignment with the eyes at the ends of the said impact bars. The supportin bar 4 is bent at its forward end and is attac ed to the channel shaped frame cross member -6 by means of a bolt 7 passing through ahole in the bar 4 which registers with a hole inthe rear downwardly extending portion of the frame the lower'portions of the'sill amen.

member 6. i The support'arm 5 is curved outouter end of the impact bars. This arm has at its forward end an inwardly projecting bracket'8 fastened to it by rivetsor other suitters with the hole '10 near the end of the cross member 6. The support arms 4 and 5 are connected by means of achannel shaped brace 12 which is shown as riveted to' the arm 4 at 13 and attached to the armt by means of the bolt14. 1 v

A brace 15 between'therearend of the arm 4 and the forward end of the arm "5 isshown wardly at its rear end for attachment to the as riveted to thearm' t a't 16iand'connected to. the arm 5'by meansof the b'olt '14'which passes through the brace 12. I I L In Figs. 1 and 3 the bracket 12 is shown as suspended from the body o f'the'automobile in the followingniann'er: N eartheouter edge of the bracket 12 there isja hole 12 which,

registers with a hole 11' in the metal body sill 11 and with a hole 18 in the floor plate 18. A

bolt 17 is passed through the' holes i'n the members 11, 12am} 18 and through a channel shaped bearing plate 19. The bearing plate 19 is shown with its outer leg shorter than its inner leg in order to bear equally upon the uneven portions of the floor plate 18. By means of. the bolt 17 the -bearing plate 19 the bracket 12 is held rigidly against of. the auto mobile body.

.Fig. 4 shows the manner of suspending the- -bracket' 12 from a'gusset plate20 at the rear corner of the body frame. The bracket 12 is. I

shown'with an elongated hole 21 and the'gu'sset plate 20 has a holexdirectlyabove thelhole 21., A bolt 22 "is passedthrough'the'hole' in the gusset plate and thehole 21 and the bump- I I er is held'rigidly against the body sill member 11 by meansof said bolt 22.

Fig. 5 shows-another modification of the mannerof suspendin g'the bumper from the 'body sill. In, this figure the body sill 11", which may be\of wood, is shown directly above the bracket 12. A lag screw may be passed through the-elongated hole 21' and emedded in the wooden body sill- 11". r When the bumper is attached to the auto ios- mobile the member 15 will the rear end c of the bumper and thereby preventhorizontal vibration of the bumper. It will also transmit a part of the load to the front of the bumper support in case a blow is struck against the impact elemezt. The bracket 12 acts both as a brace between the sup rt arms 4 and 5 and as a convenient means or rigidly appending the bumper from the automobile y Our invention is particularlyuseful when it is necessary to support an impact element "at a considerable distance from the frame of t-ance mm the car frame, and with freedom p from vertical and horizontal vibration.

In the drawings a bumper is shown for protecting only one fender, It vis-clear that a second bumper may be supported at the i opposite side of the automobile for protec-- 3 other.

I 1 1 ment is convenient for the packing and shipment may differ from that shown in the" tion of the other rear fender. Identical elements could be used for the bumper on the having a lateral frame member, of an im-- opposite side, the only difference being in t e manner of assembly. The brace 15 is shown as detachably connected to the sup: porting arm5 by the bolt 14. This arrangeing of the bumper but the connection may be made by any other suitable means.

It is apparent that the bumper impact eledrawings. "One or more than two impact bars could be substituted for the bars 1 and 1'. Also the pin-and-eye connection at, the ends of the bumper bar could be sup-planted b other suitable connections. Furthermore tli e impact surface might be extended to cover the entire rear of the car and thereby afford protection to the spare tire and the central portion of the car.
